RAILWAY Brahim-SHOE.

Specification of letters Patent.

l Patented Aug. 18;-1908.

Application filed January 11, 1908. Serial No. 410,399.

To all whom 'it may. concern."v

Be it known that l, JAMES-S. BAKER, a citizen of the United States,residing at Altoona, inthe county of Blair andA State of Pennsylvania,have invented 'certain new and us'ei'ul Improvements in- Railway Brake-Shoes, of which the following is a specification. f

This invention relatesto railway brakes, and hasnarticular reference totheprovision of a brake shoe for railway cars, the construction beingsuch that all danger of breakage of the shoeor the same becomingdetached from the brake beam, tending toA cause derailment of the train,will be reduced to the minimum.

More definitely speaking, the invention comprises a' brake shoe made uprincipally of a east metal body portion of su stantially uniformthickness and curved -to conlorm with the curvature of the'wheel withwhich it is intended to cooperate, a tough metal plate back for the bodyportion',1of peculiar lorrn, and a novel construction of attach# v mentmeans whereby the brakeshoe is secured to the brake beam.

The mechanism whereby the ob'ects ofthe present invention are attainedw'l be better understood as this description progresses, and to thispurpose reference is to be had' to the accompanying drawings in which,

Tfigure 1 is a general perspective of a brake shoe made in accordancewith the present invention, portions being broken away; Fig. 2 is acentralA transverse section, and Fig. 3

,is a fragmentary longitudinal section o n the or dimensions, preferablyin accordance with the hi. C. B. standard, and comprises a heavy "bodyportion 10, preferably made of cast metal. In order to strengthen saidbody 10 and to provide a means whereby said body may be secured tothebrake beam and there held until substantially entirely worn outwithout any danger of breaking or dropping y to the rail, I provideatough steel plate 11 for thek said body, the said plate being providedWith a slot 12 intermediate of its ends and the ends being bifurcatedfor the purpose to be presently set forth. On opposite sides of the slotthe steel plate is struck up to form sockets 13. Thetotal width of theplate 'is slightly le'ssl than the Width of the. body 10, and the lengthof the plate is slightly less than the length of the body.

legs l5 and outwardly projecting feet 16 constitutes the immediate meansfor attachment of the brake shoe to the brake beam. The feet 16 arereceived inthe aforesaid sockets 13 and lie between the steel ,plate andthe body portion and the bottoms ofthe feet lie substaritiall;r liushwith the inner face ofthe 'said plate 1l. lt will be seen therefore that.the inner face of thevfeet and plate lie substantially parallel vwiththe inner face'ofthe Ab'ody 10, and for this reason the'bdy 10'Inay hepractically entirely rworn away before any part thereof will be allowedto dropl'froni its iastenings. `v

ln constructing the brake'shoe as herein set forth, the loop and plateare properly as- Wliich the body lportion is cast thereupon, portions ofthe metal of thebody passing through the slot 12 and bifurcations of theends of the plate whereby the ends oftheplate are embraced by the castmetal, the sockets-Band feet 16 are embedded in cast metal, and the legs1.57ct the loop are substantially embraced .by the same, whereby theloop lliis not only permanentlysecured in place by means of the-saidsockets but is prevented from distortion or rupture by the heavy'bodv ofmetal wherein itis, embedded.

While I have herein set forth the best manner of construction of thebrake shoe for all practical purposes, itis to be understood that thespeciiic details oi construction mayl be varied in certain minorparticulars so long as the spirit of the inventionis not departed from.A'
